The E19 error on your Bosch Dishwasher means the appliance has detected a water inlet or fill problem, usually caused by low water pressure, a blocked inlet filter, or a fault with the inlet valve. In most cases this can be fixed at home without calling an engineer.
| Error code | E19 |
|---|---|
| Meaning | Water inlet fault — the dishwasher is not filling with water within the expected time |
| Severity | Medium — the dishwasher will not run a cycle until this is resolved, but it is not usually a safety issue |
| Time to fix | 10–30 minutes |
| Tools needed | Adjustable pliers, small bucket or towel |
What the E19 error means
Bosch dishwashers use a sensor to check that water enters the machine at the correct rate during the fill stage of a cycle. If the water flow is too slow, restricted, or absent, the control board raises the E19 code and pauses the cycle to prevent damage or an incomplete wash.
This code almost always points to something restricting water getting into the machine, rather than an electrical fault, which is why most homeowners can resolve it themselves before considering a service call.
Common causes
- Low mains water pressure or the supply not being fully turned on
- A kinked, twisted, or trapped water inlet hose
- A blocked inlet filter where the hose connects to the dishwasher or tap
- A faulty or stuck water inlet valve inside the machine
- The kitchen tap or stopcock feeding the dishwasher being partially closed
- A worn or failing water pressure sensor (flow meter) on some models
How to fix the E19 error
- Check the water supply is fully open — Confirm the tap or valve feeding the dishwasher is turned on completely, not just partially open.
- Inspect the inlet hose — Pull the dishwasher out slightly and check the hose isn't kinked, twisted, or squashed behind the unit.
- Clean the inlet filter — Disconnect the hose at the tap or valve end, remove and rinse the small mesh filter, then reconnect securely.
- Run a short test cycle — Restart the dishwasher on a quick cycle to see if it fills normally and the E19 code clears.
- Check the household water pressure — Test another tap in the kitchen; if pressure is unusually low throughout the house, this may need addressing separately.
- Call a qualified engineer — If the code persists after these checks, the inlet valve or flow sensor may need professional inspection or replacement.
FAQ
Can I still use my dishwasher with an E19 error showing?
No, the cycle will not complete properly until the water inlet fault is cleared, as the machine needs a full fill to wash and rinse correctly.
Does E19 mean I need a new part?
Not necessarily. Most cases are caused by a blocked filter or restricted hose, which can be cleared without replacing any parts.
How do I reset the error after fixing the cause?
Turn the dishwasher off at the mains, wait a minute, then switch it back on and start a new cycle to check the code has cleared.
